17 Claims.

An object of my invention is to provide an osc ating iron forlaundering, pressing and the like, which is simple, durable andcomparatively inexpensive to man A further object ufacture. is toprovide a tool having a heated sole plate which oscillates relative tothe major portion of th e tool for the purpose of traveling over a muchgreater area of material being ironed or otherwise ment of the tool acfinished during normal moveross the material, thus reducing the amountof manual movement required in proportion to the actual over thematerial.

passage of the sole plate Still a further object is to provide a laundryiron or the like having a sole plate to which rotary oscillatory movement is imparted, the sole plate being mounted for such movement on anaxis perpendicular to the pressing surface of the sole plate.

Still a further object is to provide a compact iron comprising a casinghaving a manipulating handle, oscillatable sole plate mounted on andenclosing the bottom thereof and an electric motor carried by the casingand connected with the sole plate which is oscillated thereby during theoperation of the iron.

Still another obi the handle of the iron ect is to provide a switch inconnected with the motor vice, whereby the objects contemplated areattained, as hereinafter more fully set forth, pointed out in my claimsand illustrated in the accompanying drawing, in which:

Figure 1 is a plan iron embodying my view of an oscillating laundryinvention.

Figure 2 is an enlarged sectional view on the line 22 of Figureconstruction.

Figure 3 is a det 33 of Figure 2 to the handle of the i only limitedswiveling 1 to show internal details of ail sectional View on the lineshow a means for connecting ron to the casing and permit of the handle.

Figure 4 is an electro-diagrammatic view of the motor and heating Figure5 is a pla construction showing shape of the usual element of myinvention; and 11 view of a modified form of an oscillating iron of thedomestic electric iron instead of one having a circular outline as shownin Figure 1.

On the accompanying drawing I have used the reference numeral It toindicate a sole plate. It

is circular in shape, being preferably upturned at its periphery asindicated at l2. An annular groove M is formed in the sole plate l0within which I locate an electric heating element IS.

The heating element It is retained in position by a sheet of insulationl8 and a cover plate 20. Cap screws 22 are provided for retaining thecover plate 253 in position and clamping the sheet of insulation l 3between the cover plate and the sole plate. 10

The plate 2B3 has a tubular extension 24 in which is located a pair ofgraphite bearings 26. These rotate on a stationary shaft 28 having ahead So and mounted as by screw threading or the like in a hub 32 of acasing 3d. Thus the sole plate it is oscillatably mounted relative tothe casing 3 3.

Mounted on the casing 34 is a motor 36. A gear casing 38 is connectedwith the motor 36 within which gear casing the shaft of the motor has aworm l!) which meshes with a worm gear 42 (see Figure 1). The worm geard2 drives a crank shaft M journalled in the casing 38.

Within the casing 3d a crank 46 is secured to the lower end of the crankshaft 44 and is pro- 25 vided with a crank pin 48. An arm 50 is securedto the sleeve 26 and its outer end is connected by a link 52 to thecrank pin 48.

From the construction of the parts just described, it will be obviousthat rotation of the 30 crank 46 will impart oscillation to the arm 50and consequently tothe sole plate I 0.

For controlling the heating element I6 I provide a rheostat switch 84which is preferably of the snap acting type and operable to energize theheating element l 6 for low, medium or high heat as desired. -Within thecasing 34 the circuit for the heating element l 6 includes a pair offlexible leads I l which permit oscillation of the sole plate. Theswitch a; is consequently located adjacent a manipulating handle 86which is mounted on the casing 3 3 by means of a yoke 88, a swivel stud90 and a bracket 92. The stud 90 has a semiannular groove 94 (see Figure3), a retainer pin 9% extends through the bracket 92 for retaining thestud 90 in position yet permitting swiveling movementtherecf, thismovement being limited to approximately a half revolution due to thefact that the groove 90 is not completely annular.

The yoke 38 is provided with a Wire carrying channel Q8 and the handle86 is provided with a trigger portion Hill. The trigger is pivoted atI02 and is adapted when the handle is grasped to counter-sink into achannel I04 of the handle and in so doing to close the circuit through aWhen the handle 86 is released the push button moves back to the opencircuit position, moving the trigger I00 with it. The push button I06 isconnected in the circuit of the motor 36, thus providing an automaticcontrol which de-energizes the motor whenever the operator stops usingthe iron by letting go of the handle. Flexible leads I08 extend from theswitch I06 to the casing 34, these leads being looped as indicated atl08a to permit swiveling of the handle 86.

The current supply wires for the motor and heating element are indicatedat IIO. These may extend to a yoke II2 secured to the casing 34. i

In Figure 4 I show a wiring diagram illustrating that the heatingelement and motor are independently controlled by their respectiveswitches. The switch for the heating element is of the rheostat or someother type for obtaining different degrees of heat as desired.

In Figure 5 I show a modified construction in which the sole plate Illaand the casing 34a are in the shape of the usual household iron.

As shown by dotted lines the sole plate oscillates about the axis shownat 280. and the handle 86a is mounted in the usual position of domesticirons. The motor 36a and gear casing 380. are mounted ahead of thehandle 86a. The internal construction and operation of the modifiedconstruction is substantially similar to that described in connectionwith Figure 2.

Some changes may be made in the construction and arrangement of theparts of my device without departing from the real spirit and purpose ofmy invention and it is my intention to cover by my claims any modifiedforms of structure or use of mechanical equivalents which may bereasonably included within their scope.
